The monthly event for January 2017 is 24 stages in a 1960's vehicle. Six stages are made available each week, so if you're starting this on the first of the month, only 6 stages are available for now.

The key to successfully completing the monthly event is to exercise caution. Take it slow, as it doesn't matter where you finish, just that you cross the line in the last stage in one piece. Have good engineers who can repair your car should you take a bad bump.

Additionally, you'll unlock the Dependable achievement if you haven't already.
